Description

Technical Field

[0001] The utility model relates to the technical field of casting cleaning, in particular to a high-pressure cleaning machine for manhole cover castings. Background Art

[0002] Manhole covers are devices used to cover deep wells on roads or in homes to prevent people or objects from falling. During the casting process of the manhole cover, it is necessary to extrude casting sand to form the pattern shape of the manhole cover, and then pour it with molten iron. After cooling, the cast manhole cover needs to be lightly processed, so the sand attached to the surface of the manhole cover needs to be cleaned to prevent it from affecting the later processing of the manhole cover.

[0003] According to a Chinese patent document with the announcement number CN216262319U, a casting grit cleaning device is disclosed, which includes a cleaning box, a support platform is arranged inside the cleaning box, and a plurality of bevel gears are arranged on the support platform, one of which is connected to a first motor; a plurality of bevel gears are meshed and connected with the helical tooth surface of a turntable, and a casting is placed on the turntable; a cylinder is arranged inside the support box, and the piston rod of the cylinder is connected to a pipe, and the pipe extends upward to the inside of the casting through the support box and the turntable, and the end of the pipe is connected to a first nozzle; an outer cleaning mechanism is respectively arranged on the top and one side of the cleaning box, and the outer cleaning mechanism includes a second nozzle, and the second nozzle is arranged directly facing the casting. The cleaning device does not need to be frequently moved or turned over for cleaning, and can conveniently and quickly clean castings with inner cavities, while achieving surface cleaning of the castings, and has high cleaning efficiency.

[0004] Based on the search of the above patents and in combination with the sand cleaning device in the prior art, it is found that when the above cleaning device is in use, it can cooperate with the screw rod and the cylinder to move the first nozzle and the second nozzle, so as to clean the casting. However, in actual use, it is necessary to screw the screw rod and the nut sleeve together to drive the first nozzle to move back and forth to clean the upper and lower surfaces of the manhole cover casting. However, during the water spraying process, the screw rod will be exposed to water. Long-term use will cause the screw rod to rust, resulting in the screw rod and the nut sleeve being unable to move, thereby making the first nozzle unable to move flexibly, thereby reducing practicality.
